    Frequently Asked QuestionsMS Causes

    Is there a single cause of MS?

    There’s no one single cause of MS. Researchers have identified genes, environmental triggers, infections, and more that may play a role in causing MS.

    Is MS a genetic disease?

    MS isn’t hereditary, but genetics may still play an important role in MS. MS is not passed down from generation to generation, per se, but certain genetic risk factors probably are.

    Is MS contagious?

    No, multiple sclerosis can’t be passed from person to person. MS is not an infection, but viral infections may play a role in triggering MS. A pair of herpes viruses—HHV-6 and Epstein Barr virus—are two likely suspects.

    What causes inflammation in MS?

    MS is an autoimmune disease. The immune systems of people with MS mistakenly attack protective myelin that surrounds cells in the central nervous system. This immune response causes inflammation and damage, which leaves behind lesions that can be seen on an MRI.
